Abstract: The disclosed invention relates to an electro-optical device for use with a facsimile printer, telecopier, etc., designed to accommodate line-at-a-time output of picture information with the aid of an electrically controllable electro-optical substrate. In particular, there is disclosed a solution to the problem of adjusting the electro-optical elements to provide the desired rectilinear output of picture information. The electro-optically active substrate (1) is supported in a frame-like housing (17) such that it may be adjusted perpendicularly relative to a longitudinal edge (18) of the substrate (1) by means of an adjustable ledge (31) and a resilient support (33). A beam of light from a light source (37) is shaped and directed onto the substrate by means of a light-shape converter (36) which can be adjusted relative to the substrate by means of a cross slide arrangement (51, 57) having 2.degree. freedom.

Abstract: A system for monitoring the level of an RF signal having such a small amplitude that it must be amplified before it can be monitored. To determine the deviation of the amplifier gain from the desired value, an additional RF signal of relatively high amplitude is used and is attenuated by a predetermined amount before being applied to the amplifier. The levels of the attenuated and subsequently amplified RF signal are compared with the level of the unchanged signal. From the deviation of this ratio, the gain variation is determined.Alternatively, in lieu of gain control of the amplifier the gain variation may be mathematically offset in the digital instrumentation provided.The monitoring system is suitable for use in the so-called instrument-landing system (ILS) and in VOR and DVOR en-route navigation systems.

Abstract: An electro-mechanical load sensor is in the form of a mechanical resonant system with electrostatically coupled electrodes. The mechanical system is formed from a silicon wafer by a selective etching process and comprises a filament of between two terminations 12 and 13 carrying transverse plates M.sub.1 and M.sub.2. Electrostatic (capacitive) coupling to plate electrodes E.sub.1, E.sub.2, E.sub.3 in a self-exciting circuit drives the system. The resonant frequency for angular S vibrations with plates M.sub.1 and M.sub.2 in anti-phase varies with applied load L and is thus a measure of this load.

Abstract: A printer having a print wheel rotatable on a carriage. The carriage is guided for movement parallel to a platen. The printer may print at either a fast speed for draft quality output, or a slower speed for highest quality output. The lesser quality of output produced at the fast speed is more than adequate for draft documents.

Abstract: A zero insertion force socket for connecting the leads of an integrated circuit carrier to conductors on a printed circuit board. The socket contains a movable actuator which shifts the contacts in the socket into engagement with the leads on the carrier after the leads have been initially inserted into the socket in positions spaced from the contacts. The actuator comprises a partitioning structure made of interleaved thin metal strips which allow a very dense arrangement of the contacts in the socket and also perform an electrical shielding function.

Abstract: An audible indicator is provided for a connector which indicates when the mating connector halves are fully interengaged. The indicator is activated by an actuating pin which is mounted within the interior of the connector body. Preferably, the actuating pin is slidable in a centrally located polarizing key for the connector.

Abstract: Owing to a new design of the partition wall (vortex former) of the novel type tangential blower, there is achieved an improvement of the pressure-volume characteristic and a reduction of the noise development.

Abstract: A contact extraction tool in which a pair of spring arms may be squeezed together to force jaws on the ends of the arms inwardly through holes in the tip of the tool to firmly grip a contact therein while the tip is releasing contact retention element in a connector assembly to facilitate withdrawal of the contact from the assembly.

Abstract: A system for correcting the time of occurrence of a triggering point along the rise time of a pulse, particularly in a DME system comprising interrogator and transponder stations. Actual received pulses which may be distorted by multipath signals or other effects are compared with stored rise time reference values to generate corrections to time correct the triggering point. The correction may be transmitted between interrogator and transponder in coded form.

Abstract: This invention relates to a circuit arrangement and the associated mechanism for slaving the angles of rotation of the slats of a plurality of centrally controlled sun or window blinds. The driving motor of each blind is provided with current via a corresponding operational amplifier and related circuit. The motor operates the slats to achieve balance between an input control voltage and a voltage depending on the angular position of the slats. An automatic version in which the control voltage is generated by a photoelectric sensor and several circuit variations are shown.

Abstract: A totalizer of the decade counter type or the like which, when being pulsed, tends to drain a battery, where the battery and totalizer are remotely located. The battery thus needs to have a long life because of its remote location. The same is effected by a circuit including a voltage regulator which holds average power constant, at least from pulse to pulse.

The device is formed as a flat stamping and curved into a "bracelet" shape with closely interleaving first and second axially extending flat fingers. A base portion in the form of a ring extending about the circumference of the groove and having a first set of substantially flat, integral, axially-extending fingers spaced circumferentially and occupying substantially the entire axial dimension of the cavity.

Abstract: A releasable locking mechanism is provided for a rectangular connector in which matching grooves are formed in the outer and inner surfaces respectively of the elongated sides of the shells of the plug and receptacle halves of the connector. Elongated wires are positioned in each of the plug shell grooves. Actuating devices are located at opposite ends of the plug shell which act against inwardly extending legs on the ends of the wires for shifting the wires outwardly to become partially lodged in the grooves in the receptacle shell thereby positively locking the connector members together. The actuating devices may be retracted to allow unmating of the connector halves.

Abstract: In a fiber optic connector element two or more fiber optic cables are each terminated in a ferrule whose end contains a beam expanding lens. The ferrules are tapered and each of them fits into a correspondingly tapered hole in an insert within the body of the connector element. The ends of the ferrules are substantially in the same plane and are adjacent to a transparent window which is mounted in a bezel surrounding the insert. When two such connector elements are mated, their windows are close to each other and parallel to each other, and each ferrule in one element is optically aligned with a ferrule in the other element. The casings and bodies of the connector elements may be constructed hermaphroditically.

Abstract: A clamp is disclosed for a fiber optic cable having metal strength members. The strength members are fed through axial slots in the forward end of an inner sleeve of the clamp and are wound helically around the inner sleeve. Thereafter an outer sleeve is crimped around the helically wound portions of the strength members and the inner sleeve to tightly secure the strength members to the sleeve.
